0xC8

0xC8 is a hexadecimal numeric literal, using the 0x prefix common in many programming languages to denote a base-16 value. The hex value C8 equals decimal 200 and has a binary representation of 11001000. Such literals are widely used in computing to specify exact 8-bit values, bit masks, color components, and memory addresses.

In practical use, 0xC8 appears in a variety of contexts. As an 8-bit component, 0xC8 can represent a channel value of 200 in color models that use 0–255 ranges, and it may be part of larger values when combined with other bytes in multi-byte data.

In character encoding, 0xC8 has different interpretations depending on the encoding. For example, the Unicode code point U+00C8 corresponds to the Latin capital letter E with grave (È). In single-byte encodings such as ISO-8859-1 or Windows-1252, the single byte 0xC8 maps to a specific character, which may differ across encodings.

In assembly language and machine code, 0xC8 has architecture-specific meanings. On x86 processors, the opcode 0xC8 corresponds to the ENTER instruction, which allocates stack space for a procedure. In the 6502 microprocessor, 0xC8 represents the INY instruction, which increments the Y register. These usages illustrate how the same two characters can encode very different operations in different instruction sets.

Overall, 0xC8 is a concise representation of the value 200 in hexadecimal notation, with several notable interpretations in programming, encoding, and processor instruction sets.
